Book Description
This volume of the Handbook of Zoology summarizes "small" groups of animals across the animal kingdom. Dicyemida and Orthonectida are enigmatic parasites, formerly united as "Mesozoa" and their position among the multicellular animals is still not known with certainty. Placozoa are small, flat marine animals which provide important information on metazoan evolution. Comb jellies (Ctenophora) are esthetically fascinating animals which cause considerable discussion about their phylogenetic position. Seisonida are closely related to rotifers and acanthocephalans. Cycliophora were discovered and described as one of the last higher taxa and surprise by their complex life cycle. Kamptozoa (= Entoprocta) are small sessile animals in the sea and sometimes also in freshwater. Arrow worms (Chaetognatha) play an important role as predators in the plankton, but they also include benthic forms. Pterobranchia and acorn worms (Enteropneusta) belong to the deuterostomia and are related to echinoderms. In particular enteropneusts play an important role in understanding deuterostome evolution. These chapters provide up to date reviews of these exiting groups with reference to the important literature and therefore serves as an important source of information.

Seasonal Abundance of Aquatic Invertebrates and Their Utilization by Hatchery-reared Rainbow Trout
Author: Harry D. Kennedy
Publisher:
ISBN:
Category : Fishes
Languages : en
Pages : 44
Book Description
A 2-year study of the composition of bottom fauna, its seasonal and annual variations, and its utilization by hatchery-reared rainbow trout was made in experimental stream channels of Convict Creek, Mono County, California. Three orders of aquatic invertebrates, Trichoptera, Coleoptera, and Ephemeroptera, comprised 70 percent of the total bottom fauna. Terrestrial insects were an important food source between June and November but were absent from the diet between December and February. Forage ratios and frequency of occurrence of the primary food organisms is given. Post-hatchery survival of rainbow trout in small high altltude streams appears to be more dependent upon the physical condition of the trout at time of stocking than on a highly favorable physical environment.
